WATERPROOFING
BERWYN ROOFING COMPANY

Waterproofing Services in Berwyn, IL

 

In Berwyn, even a small leak can turn into a big problem—fast. Our homes and buildings go through constant stress from rain, snowmelt, and temperature swings, and without proper waterproofing, it’s only a matter of time before that moisture finds its way in.

​

At Berwyn Roofing Company, we believe in preventing problems before they start. That’s why we offer tailored waterproofing solutions for roofs, walls, flashing, and more. Whether it’s an older two-flat or a new build, we’ll help keep your building sealed, dry, and secure.

​

​

Why Waterproofing Is Worth It

When moisture slips through a seam or flashing, it doesn’t just wet the surface—it soaks the insulation, invites mold, and leads to energy loss. Long-term, it eats into your structure, causes odors, and shortens the lifespan of your roof system.

​

Waterproofing keeps all of that at bay. It protects your investment, saves you from major repairs, and helps your roof and exterior last longer—especially in Berwyn’s storm-prone seasons.

​

​

Where We Apply Waterproofing

• Flat and low-slope roofs

• Around skylights, vents, and AC curbs

• Wall-to-roof intersections

• Parapet walls and roof edges

• Drainage points and scuppers

• Deck or balcony transitions

• Masonry joints and capstones

​

Waterproofing Methods We Use

 

Liquid-Applied Membranes

We roll or spray on a thick, rubberized coating that cures into a seamless barrier—no seams, no cracks, no water entry points. Ideal for older flat roofs and surfaces with irregular shapes or hard-to-reach joints.

​

Elastomeric Roof Coatings

These coatings are built to move with your roof. They stretch during temperature changes and return to form without cracking. Great for Berwyn’s hot-cold weather shifts and rooftops that get full sun exposure.

​

Sealants & Flashing Wraps

We reinforce every flashing edge, vent pipe, and joint with heavy-duty commercial sealants. For high-risk areas, we add reinforcing mesh or wrap to make the seal extra strong and durable.

​

Cementitious Waterproofing

This cement-based coating bonds to masonry, brick, or concrete—perfect for parapet walls or older masonry features. It stops water while still allowing the wall to breathe and adjust to temperature changes.

​

Reinforced Roof Coatings

These multi-layer systems are built to last, combining a base membrane, embedded fabric, and a topcoat. They’re strong enough for foot traffic, equipment pads, and rooftop areas that see extra wear and tear.

​

​

Signs You May Need Waterproofing

• Soft or bubbled areas on your flat roof

• Ceiling stains or peeling interior paint

• Rust around rooftop hardware

• Visible cracks in sealants or mortar joints

• Persistent attic humidity or mildew smells

• Ponding water that takes too long to drain
